To all whom it my concern: Y

Be it lrnown'that l, MARTIN Nns'rnn, a

resident of Detroit, in the county of Wayne. and State of Michigan, a citizen of the United States, have invented certain new and useful Improvements in Dumping Bodies, of which the following is a specification.

My invention relates to improvements in dumping bodies and refers particularly to a dumping body; capable of connection with a frame or support and automatic to a degree in its operation of dumping and re turn to normal osition.

The main ob ect of my vinvention. is the provision of a structure which may be supported upon suitable traction means to be transported to the desired placeof use and which will operate with ease and facility 1s secured the pair of ears 7, provided with slots 8, in which moves the pin or keeper 9,

and automatically. Y

Another object of my invention is the pro- .vision of a dumping hody construction which can be easily transported and which will be of simple, durable and inexpensive construction and thoroughly efiicient and-reliable inoperation, to produce a practical and useful mechanism of this character To attain the desired objects and such others as inhere to an invention of this character myi invention consists of av dump I ing apparatus emhodyingnovel features 0t frame adjacent the pair of racks and is proconstruction' and combination'of parts substantiall as shown, described and particularly de ned by the claim.

In order that the construction in detail and the operation of my invention may be more clearly understood and its many advantages'be fully appreciated I have shown in the accompanying drawings a dumping apparatus constructed according to my! invention and in said drawings; I

Fig. i represents a perspective view of the body or scoop and a. portion of the frame upon which it is mounted the body being in w normal 'position'.

Fig. 2 represents a side elevation with the parts in a position they occupy when the hodijgiassumes dumping position,

t i'g. 3 represents a side elevation with the parts in normal or unduinpedattitude, and

represents a top plan view of the sup orting :Erarne, guide racks and the mechanism tor retaining and releasing the scoop or hody.

ing provlded between the toothed plates and 5' represents a view of the inner wall or end oithe bucket or body.

Referring by numeral to the drawings in whichthe same numbers are employed to 1 denote the same parts in all the views:

The numeral 1 designates the rectangular elongated supporting frame, which may he mounted upon a suitable traction means or truck for transporting the apparatus to the desired alace, the frame at one end being provide with depending hoolrs forming stops or abutnaents 2,fwhile strips S'are secured to the frame by fastenings 42, to space said strips frornthe frame to receive the pins or studs 5, which provides a pair of racks, the'purp'oseoi which will presently appear, r

Also mounted in the frame at a suitable oint thereon are the cross pieces h, to which vided with a rear vertical wall 15 and a front inclined dumping portion or wall 16 and uponthe inclined wall is secured the pair of curved strips or loloclrs 1?, which are made preferably of wood or suitable cushioning material and to said blocks are secured the curved geared or toothed plates 18, which are adapted to engage or ride u on the pair of racks of the frame, said 95 toothed plates being tormed'at oneend with heads 19, adapted as seen in Fig; E2 to en-= gage the stop of the frame to limit the movement of the scoop in its dumped position, a spring and chain connection 240, be its frame, while the vertical wall of the scoop carries stops 21,'wl1ich are adapted to en gage the frame, said vertical wall also can rying the inclined arm 22, formed with a ton hoolr23 to he engaged by the keeper i sustaining the parts in the esition sl win in 3, the huclret heieo in.

movement and returned to normal position by the chai'nQ l, and intermediate spring 25 which in connection with the spring and chain connection 20, 20, provides an automatic action for said scoop or body.

The operation of my automatic dumping body! will be readily understood from the description when taken in connection with the drawings and attention is called to Fig. 3 which shows the arts in normal position with the scoop rea y to be filled and when the scoop has been tilled it is simply necessary to move the spring actuated latch which releases the book 23 and permits the scoop to assume the dumping position shownin Fig. 2, the connections between the scoop and frame causing the body or scoop to automatically return to normal position after j theoperation of dumping.

lltwill "thus be seen that I provide a dump.- ing apparatus which is automatic in its action, or returns to normal-position as soon as the dumping has been effected, also that the structure'as a whole is simple, compapt t and durable, and capable of production a comparatively low price; also that the apparatus may be readily carried upon a truck and that, generally, the construction will provide an eiiicient, desirable and practical dumping apparatus.

It will be noted that the bucket or body '14, is provided with the bufi'er or stop 21, which consists of two vertical parallel mom-J 1 ,asa iev here, as shown in Figure -5, which form counter balance weights, and also that the vertical and long inclined end wall, an armextending downward from said vertical wall and formed with a hook, a sliding catch engaging said hook, a slotted guide for said catch and secured to the track, a spring for holding the catch in locked position and for returnlng it to normal-position, a hand lever fulcrumed to the track and connected to the latch for releasing said latch, and a sliding rod mounted under the track connected with the lever and normally engaging the hopper, said rod being moved by the lever to release it from the hopper to permit tilting of said be per.

n testimony whereof I hereunto afiix my signature.
